997109 - Some SVG animatemotion paths are wrongly followed, depending on their points

Status: RESOLVED DUPLICATE of bug 987077

(Core :: SVG, defect)

Description

[Vincent MONIER]

Attachment: screw-some-curved-paths.svg

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:28.0) Gecko/20100101 Firefox/28.0 (Beta/Release)
Build ID: 20140314220517

Steps to reproduce:

Create a SVG document using animatemotion on an element, and use a curved path (C)
It also happens with some other curved paths (Q for sure, maybe A, T,...)


Actual results:

Depending on the curved path values, the animated element will, or will not, follow the path.
Sometimes, "not following" means "moving the somewhere that doesn't make any sens on the SVG canvas" (C) sometimes, it means "moving directly from start point to end without considering the curve (Q).


Expected results:

The element should follow the path. The path itself is correctly drawn when using the same values inside the path/@d attribute.
Chrome correctly do the animation: the element follows the curved path, regardless the values or the "C *,* *,* *,*" path curve.

This should be fixed by Bug 987077

Comment 2

Yup, verified WORKSFORME in trunk, but broken in aurora.

Perhaps we should mark as dupe of bug 987077, since it's the same underlying problem? (rather than tracking/blocking as independent regressions)

Comment 3

[Sylvestre Ledru [:Sylvestre]]

Not tracking. We are already tracking bug 987077.

Comment 4

[Daniel Holbert [:dholbert]]

Duping, per comment 2 (& comment 3).

(The symptoms are slightly different, but it appears to be the same underlying bug.)
